The Yankees' chances at winning the World Series jumped to 10-1 Wednesday, according to Bovada.com, a gambling website. It was the league's third-highest.

It was the same day the team signed Tanaka, 25, of Japan, to a seven-year, $155-million deal. The starting pitcher was the team's fourth big-money offseason signing, a list that also includes Carlos Beltran, Jacoby Ellsbury and Brian McCann.
